 Keywords:  bigsur      |       Port:  molmol
------------------------+-----------------------
 molmol does not build on macOS 11 or later:

 https://build.macports.org/builders/ports-
 11_arm64-builder/builds/20187/steps/install-port/logs/stdio
 {{{
 make[4]: *** No rule to make target `/usr/lib/libz.dylib', needed by
 `molmol'.  Stop.
 }}}

 System libraries like /usr/lib/libz.dylib are not present in the
 filesystem anymore as of macOS 11. They are only in the dylib cache, so
 you can dlopen them, but you cannot do things like use them as depenencies
 in makefile rules anymore.

 molmol shouldn't be using /usr/lib/libz.dylib anyway. It should use
 MacPorts zlib.
